2022年6月英语六级考试真题真正完整版 Consider Paul Krugman writing breathlessly in the New York Times about the “rising incidence of extreme events,” He claims that global warming caused the current drought in America’s Midwest, and that supposedly record-high corn prices could cause a global food crisis. But the United Nations climate panel’s latest assessment tells us precisely the opposite. For “North America there is medium confidence that there has an overall slight tendency toward less dryness” Moreover, there is no way that Krugman could have identified this drought as being caused by global warming without a time machine; Climate models estimate that such detection will be possible by 2048, at the earliest. And, fortunately, this year’s drought appears unlikely to cause a food cri sis, as global rice and wheat supplies retain plentiful. Moreover, Krugman overlooks inflation: Prices have increased six-fold since 1969. so, while com futures(期货) did set a record of about S8 per bushel(葡式耳)in late July, the inflation-adjusted price of corn was higher throughout most of the 1970s, reaching 516 in1974. Finally, Krugman conveniently forgets that concerns about global warming are the main reason that corn prices have skyrocketed since 2005. Nowadays 40 percent of corn grown in the United States is used to produce ethanol（乙醇）,which does absolutely nothing for the climate, but certainly distorts the price of corn—at the expense of many of the world’s poorest people. Bill Mickbben similarly worries in The Guardian about the Midwest drought and corn prices. He confidently tells us that raging wildfires from New Mexico and Colorado to Siberia are “exactly” what the early stages of global warming look like. In fact, the latest overview of global wildfire suggests that fire intensity has declined over the past 70 years and is now close to its preindustrial level.
